Food refrigerator to use plastic wrap it
Most of the food stored in the refrigerator food is best wrapped with plastic wrap, because the plastic wrap can make the food to maintain moisture, odor isolation, longer shelf life, a large number of bacteria in the refrigerator to prevent bacteria into the food.Although most of the food put The preservation of the refrigerator when you need to use plastic wrap, but does not mean that all the food with plastic wrap.For example, chives, radishes, cucumber these vegetables, when these vegetables wrapped with plastic wrap late vitamin content than unwrapped vitamin content loss Larger.Another cooked food, hot food, greasy food, especially meat, it is best not to use plastic wrap packaging storage, these foods and cling film contact, it is easy to make the material contained in the chemical composition of volatile, dissolved To food, it is bad for health.
Common misunderstanding of refrigerator storage of food
1, raw food cooked together
Food is not raw and cooked mixed together to maintain health. According to food storage time, temperature requirements, rational use of the space inside the box, do not put food directly on the evaporator surface, to be placed in the vessel, so as not to freeze on the evaporator , Inconvenient to remove.
In addition, the various types of food should be placed in the refrigerator.New food and cooked food should also be placed separately to prevent cross-contamination, avoid mixing raw and cooked.Preferably, the hot food wrapped in plastic wrap to prevent freeze-dried food , Mutual pollution.Fruit should be scrub clean and then stored in the refrigerator.Don't store too much food, storage of food surface and the inner temperature difference is easy to degenerate.
2, wrap plastic wrap, bacteria more
If you put food directly into the refrigerator, it will increase the chances of bacteria in other food in the refrigerator.In addition, sealed with bacteria-free cling film can also reduce the moisture loss of the food section, play a fresh effect.
Experts say, do not use ordinary plastic bags of food .An ordinary plastic bags can not seal the food, and secondly its composition of ethylhexyl amine (DEHA) is easy to precipitate, can cause cancer .It is recommended PC, PE, PP and tempered glass Safety materials, the general temperature range -20 ~ 120 ℃, can store the refrigerator, but also put microwave ovens.
If you want a more perfect preservation effect, crisper is the best choice: 'Cling film and storage bags durability and sealing is poor, and can not avoid food flavor, and qualified containers are basically free of harmful substances, To a certain extent, to prevent the flow of gas and moisture loss, longer time to keep food fresh.
